Abstract
The invention discloses an injection molding machine motor temperature control mechanism. The injection molding machine motor temperature control mechanism comprises a servo motor, an injection molding machine controller, a temperature sensor, and a fan. The fan is installed on the servo motor. The temperature sensor is installed in the servo motor. An output signal of the temperature sensor is transmitted to the injection molding machine controller. The injection molding machine controller can control a switch of the fan according to signals of the temperature sensor. The injection molding machine motor temperature control mechanism can improve stability and reliability of a working state of an injection molding machine motor and has energy-saving effects.
Description
Technical field
The present invention relates to injection machine and produce a kind of control technique that plastic products carry out motor temperature control.
Background technology
Injection moulding is as a kind of main machine-shaping process, and its product has the advantages such as the large-scale production of being easy to, lightweight, Stability Analysis of Structures and low price.Along with developing rapidly of China's plastics industry, because injection machine work is unstable, cause the production schedule to be upset, the impact that causes becomes increasingly conspicuous, and especially produces the enterprise of auto parts machinery, therefore the stability of producing machine tool has been proposed more and more higher requirement.
Because the injection machine production environment is abominable, twenty four hours running every day, the motor operating mode of injection machine is complicated, so that the motor cooling fan of a lot of injection machines is done sth. in advance because operating with full load to damage, because can not in time know the motor cooling fan damages, the thing that causes electric motor of injection machine to be burnt occurs repeatedly, and makes the loss extension.
Summary of the invention
Technical problem to be solved by this invention is to provide the electric motor of injection machine temperature control device for the above-mentioned deficiency that overcomes prior art, to improve stability and the reliability of electric motor of injection machine duty, also energy-saving effect can be arranged simultaneously.
The present invention solves the problems of the technologies described above the technical scheme that adopts: the electric motor of injection machine temperature control device, comprise servomotor, controller of plastic injection molding, temperature sensor, fan, fan is installed on the servomotor, mounting temperature sensor in the servomotor, and described temperature sensor output signal is linked in the controller of plastic injection molding, controller of plastic injection molding is controlled Switch for electric fan according to temperature sensor signal.
Alarm also is set, controls alarm signal to alarm by controller of plastic injection molding output.After the temperature of the temperature sensor on the servomotor surpasses setting value, controller of plastic injection molding output alarm signal, alarm equipment alarm.
Controller of plastic injection molding is also controlled the action of servomotor.Behind the servomotor overtemperature, controller of plastic injection molding output stop signal stops the work of servomotor.
In the groove of said temperature installation of sensors on the shell in the middle of the servomotor, can measure better like this temperature of servomotor.
Set temperature display also, controller of plastic injection molding output temperature signal displays temperature to the temperature indicator can be seen the temperature of servomotor so intuitively.
Compared with prior art, the invention has the advantages that: the present invention is owing to pass through the temperature of the motor in detection and the controlling run, the one, changed the blindness in the original motor temperature control method, once opening the work of motor cooling fan, cause the motor cooling fan to damage because of overwork; The 2nd, improve the not intuitive of original motor temperature control method, the real motor temperature that shows is investigated problem easily when the injection machine operation interface; The 3rd, stability and the reliability of raising electric machine operation state reach effect energy-conservation and the minimizing noise.
Description of drawings
Fig. 1 is the motor temperature controlling organization schematic diagram of the embodiment of the invention.
Fig. 2 is the motor temperature control procedure design sketch of the embodiment of the invention.
The specific embodiment
Embodiment is described in further detail the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, in the intermediate case of servomotor 2 temperature sensor 1 is installed partly, is measured the servomotor temperature; The signal output of this temperature sensor is connected to temperature keyset 6, temperature is carried out the processing such as filtering and amplification, passes to controller of plastic injection molding 4; Controller 4 is processed according to the computing of setting, and the work of motor cooling fan 3 is controlled in output, and sends the motor temperature value on the temperature indicator 5 demonstration.
Above-mentioned servomotor 2 can have several, and equal mounting temperature sensor 1 is measured motor temperature in each servomotor.
The said temperature sensor signal is linked on the temperature switching version, after filter amplifying processing, signal is passed to controller 4, and the controller output point opens or closes by Control motor cooling fan 3.
The signal of the temperature sensor 1 in the present embodiment is input in the controller of plastic injection molding 4 after excess temperature keyset 6 changes and controls, can also there be other modes that the signal transition of temperature sensor 1 is become control signal, also can directly in controller of plastic injection molding 4, carry out conversion and control, since comparatively common, be not described in detail in this.
The temperature value that the said motor cooling fan is opened and closed arranges according to actual, when motor temperature is opened temperature greater than the motor cooling fan that arranges, then drive the motor cooling fan, when being lower than motor cooling fan temperature, motor temperature closes the value of setting, postpone the regular hour, for example close the motor cooling fan after one minute.
As can see from Figure 2, through control of the present invention, servomotor can keep relatively stationary temperature, prevents that electric fan from working long hours, energy savings.
When motor temperature surpassed setting value, controller 4 was to alarm (not shown in FIG.) output alarm signal, and alarm gives the alarm, and stopped the injection machine action and cut off machine operation
